Mtd trans no reverse?

I have a mtd and the transmission will not go in reverse.It goes preffectly normal if forward and neutral works but when i shift it into reverse nothing happens.Any idea what this could be?

MTD's can get debris/rust built up by the shifter - basically all it is is a small shaft with 3 indents - a lil metal ball locks it in each position. Try spraying PB blaster or rust buster near the shifter into the trans first, make sure its clean.

Sometimes this gets all gummed up and causes issues. MTD transaxles are super simple to tinker on - i have a few i opened ( and one currently) - the only difficult thing is making sure the detent ball doesnt get lost - make sure the top of the transaxle is removed first -

i had the same problem, my shifter ended up being hooked up wrong to the transmission. did it just now start acting up?

Reverse has never work the best sinve the po opened it to add new grease?There is a adjustment bar for the shifter i will try adjusting it and get back to you guys
